Bitcoin 30 series graphics card

Why use graphics card to mine

compared with CPU, GPU is used for general purpose calculation. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance is much stronger than that of CPU. p> However, as we have mentioned before, a card is very suitable for general computing such as virtual currency because it has many stream processors, and the speed of obtaining specific solutions is much higher than that of N card. Therefore, many miners rush to buy a card to calculate virtual currency for profit

of course, with NVIDIA's Pascal graphics card, n card's ability in mining virtual currency is not as different as a card before. So in the current situation that a card is generally out of stock, those mid-range N cards have become the second choice for miners

What are the disadvantages of mine card

finally, I want to talk about why we can't choose mine card when we are shopping for second-hand cards. Because the miners are mining bitcoin, the most important thing is to seek profits. Therefore, the graphics card they use is running and calculating all the time, and its strength is far greater than that of daily game applications. In other words, running such a calculation for one day is equivalent to running a graphics card for one month

in addition, the places where virtual currency is mined are mostly the places where multiple graphics cards gather. Thousands of graphics cards are constantly calculating in a room, and their heat is also quite huge. Miners can not choose the chassis with good heat dissipation conditions like ordinary consumers, so that the heat can be released smoothly. In this way, the graphics cards can still operate for 7 * 24 hours under high temperature conditions, It also deepens its aging degree

the result of doing so is that the graphics cards used for mining are lost prematurely. If you buy these graphics cards, the result will be unstable operation, restart and other things will continue to happen

moreover, at present, manufacturers also have strict requirements on mine cards, such as banning second-hand sales and shortening the shelf life. If users buy these mine card graphics cards, future maintenance will also be a big challenge

2. After high-speed computing with the computer composed of AMD graphics card, bitcoin can be generated
1. Unlike most currencies, bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm and is a virtual currency
2. In order to get bitcoin, you have to use computing machines, many of which are provided by AMD graphics card with high computing power. When bitcoin was hot, AMD's graphics cards were always in short supply, such as HD 7850, HD 7870, HD 5850, HD 5870, R7 270, R 280x, which are the best helpers of bitcoin
3. Later, when someone invented a mining machine that could get bitcoin more quickly, these graphics cards slowly withdrew from the mining stage
in other words, the computer made up of AMD high-speed graphics card was once the main platform for acquiring bitcoin. This is the relationship between them.

3. It's OK. It's easy to use. There are 1960 information type blockchain networks in China and more than 90000 overseas. You can see a lot of information blockchain websites such as "blockchain XX network" directly through the domestic network "blockchain network".

4. This is legal in some countries, and the domestic attitude is not very clear. Anyway, it is not illegal

5. After the completion of MLM or identification, it is important to remember that under no circumstances can you remit money first, whether it is franchise fee, deposit or other name,

6. A distributed ledger technology of blockchain! The jester of ether doesn't know what it is, so we should be cautious

7. Generally speaking, AMD's graphics card is more suitable for the most mining graphics card e to the factors of architecture, price and so on
hd7990 is the current king. It is said that the electricity charge for mining each bitcoin is 130-140 yuan. In other words, a monster card like hd7990 needs to work for about 20 days to get a bitcoin. A bitcoin may consume 300 watts of power, not counting the loss of computers
in addition to the graphics card, other hardware of the mining platform will also consume electricity. CPU / motherboard, memory, hard disk, including the power supply for the whole machine, will still need electricity because there is no 100% conversion rate. Compared with the display that can be turned off in pure standby, they have to intervene
the faster the graphics card mining speed is, the less unnecessary power consumption will be consumed for each bitcoin acquisition. In this case, the graphics card with fast computing speed often has more advantages. If a multi card platform is established, the net profit per unit time will be higher
the lower the performance of the card, the more power it consumes on average
in a word! Investment must be cautious.

8. Rtx3090 is all in stock, no need to grab
the others are out of stock. It depends on when bitcoin collapses.
